Uranium — How Is It Mined?

Open Pit MiningUnderground MiningMillingIn-Situ RecoverLinks to More InformationFor both traditional underground and open pit mining, the rocks may have only a few percent (normally <0.3%) uranium in them. The uranium then has to be removed from the rock and concentrated. The milling process involves crushing and pulverizing the rock into very fine fragments and adding water to create a slurry. This slurry is then mixed with sulfuric acid or an alkaline solution to release the uranium from the host rock. Normally approximately 95 - 98% of the uranium can be recovered from the host ro
